Ho Michael,
after some attempts I managed to restore the CustomUI.
Unfortunately I still have error messages with some scripts (see photo)

- Obj Library = Operation failed - Line 0
- Ext Scripts = dto.
- Snapshots = dto. + Background changes to white, Language changes from German to English

Have you got a clue for me?

And some icons are still missing....
Do you have any idea where I could look for it?

thanks in advance
